Re: [Discuss-gnuradio] Where to start in learning to develop and contribute to GNU Radio?

[Martin Braun]

Hey Ken,

welcome to the crew, and I'm happy to hear you're interested in
participating.
Let me add to Marcus' email:

First of all, we have a page for people like you:
http://gnuradio.org/redmine/projects/gnuradio/wiki/Development.

Yeah, hold back on that. Even if it were simple, deep architectural
changes like this need to be discussed. We have monthly calls you can join.

Make sure you've read all there is on the wiki.
Something we want to do is to port all Python blocks to C++, maybe
that's a good place to start. I think the FM pre-/de-emphasis blocks are
among those, if you want a place to start.

Have fun, and come back here for questions!
